You dont have to be a presidential candidate to have a debate. If you are a kid, you can stage a debate in the classroom or at home.
Pick an issue that has two clear sides. (For example: Should middle-schoolers get recess time?)
Before you start your debate, ask classmates (or family members) how they feel on the issue. After the debate, see if they have changed their minds. Here are some tips:
Research the issue. If, for example, you are going to make the argument that middle school students should have recess because they need the exercise, make sure you can talk about the benefits of exercise.
Guess what the other side will say. In a debate, the idea is to convince people that you have the correct position. If you think that the anti-recess side will argue that the time could be better spent learning math facts, explain why 20 minutes of exercise is more valuable than 20 more minutes in the classroom.
Use humor. Its important to have the facts, but people may be more likely to support a position if they like the person. Making them laugh is a good way to make them like you.
